RADIATOR.

SPECIFICATION forming part of Letters Iatent No. 621,114, dated March14,1899.

Application filed April 9,

To all whom it may concern:

Be it known that we, NICHOLAS MAINZ and GEORGE J. ZELLER, citizens ofthe United States, residing at Vashington Heights, in the county of Oookand State of Illinois, have invented certain new and useful Improvementsin Radiators; and We do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to radiators; and it consists in the novelconstruction and combination of the parts hereinafter fully describedand claimed. p

In the drawings, Figure 1 is a vertical section through the radiator.Fig. 2 is a sectional plan view taken on the linex in Fig. l. Fig. 8 isa detail View of a portion of the damperplate. Figs. 4, 5, and 6 arevertical sections showing modifications of the radiator shown in Fig.l1.

A is the outer casing or shell of the radiator. p B is the bottomplate-,and O is the top plate. The top and bottom plates are secured tothe shell in any approved manner. The shell is shown of oval form; butit may be made of any other approved form-7 such as rectangular orcircular, and it and the top and bottom plates may be made ofwrought-iron,cast-iron, or any other approved material which is a goodconductor of heat.

D are vertical heating-tubes which pass through the radiator and havetheir end portions secured to the top and bottom plates in Yany approvedmanner.

crosswise of the shell and longitudinally between the heating-tubes atthe middle p art of the radiator. This damper-plate has flanges e at itstop and bottom, and the said flanges have holes e', so that they mayslide freely upon vertical guide-rods E', secured to the top and bottomplates. The rods E also serve as stays or braces for the said top andbottom plates. The damper-plate is shorter than the shell of theradiator, and means for raising and lowering it are provided.

F is a crank-shaft which is journaled in 5o bearings in one of theheating-tubes and in the radiator-shell, and f is the crank-arm pro'-1898. Serial No. 677,021. (No model.)

vided with a crank-pin f', which engages with the horizontal slot of aguide or projection G on the damper-plate.

H is the inlet-pipe for the products of combustion or hot air from anyapproved form of Aheater, radiator, or furnace, and H is theoutlet-pipe. The pipes H and H -are arranged `one on each side of thedamper-plate and are connected to the radiator in any approved manner.

In the form of radiator shown in Fig. 1 the inlet-pipe is connected tothe bottom plate and the outlet-pipe is connected to the top plate.

I is arernovable portion of the outlet-pipe, which depends within theradiator. This pipe I may be a mere extension or prolongation of theoutlet-pipe; but it is preferably a separate extension-pipe connected tothe outletpipe proper. The opening or open end of the pipe I is arrangednear the bottom plate.

The hot products of combustion pass through the radiator in thedirection of the arrows shown in full lines when the damperplate islowered, and the shell and heatingtubes are heated for their fullheights and form heating-surfaces for the surrounding air which is incontact with them.

When the damper-plate is raised to the position shown in dotted lines,the hot products of combustion pass under it and are not forciblybrought in contact with the upper parts of the heating-tubes or shell.The damperplate can be supported in intermediate positions, if desired,so as to regulate the heat irnparted to the surrounding air. A singledamper suffices to regulate the heat, and the draft 'or outlet can neverbe obstructed or diminished by it.

In order that the radiator may be applicable to various situations,openings K are formed in the top or bottom plates, or in both plates,opposite the openings where the ends of the inlet and outlet pipes areconnected to the plates. Each opening K is provided with a cover 1c forclosing it when not in use, and when the inlet or the outlet pipe isremoved the opening from which it is disconnected is covered by asimilar cover k. The outletpipe of the-radiator is connected to a iiueor chimney, or it may be connected to another radiator, of which it thenforms the inlet-pipe,

IOO

and as many radiators as desired can be joined together in a series inthe same room or in the different rooms of a building.

In the modification shown in Fig. 4 the inlet and outlet pipes are bothconnected to the bottom plate and the openings in the top plate areclosed.

In the modification shown in Fig. 5 the inlet and outlet pipes are bothconnected to the top plate and the openings in the bottom plate areclosed.

In the modification shown in Fig. 6 the inlet and outlet pipes are bothconnected to the top plate of the radiator, but the radiator is invertedand supported from the ceiling of the room.

M is an outer casing for the radiator, and m is a short pipe which formsa direct connection between its inlet and outlet pipes. A damper on isarranged in the pipe m so that the products of combustion can be leddirect from the inlet-pi pe into the outlet-pipe, if desired.

N is a heating-register in the ceiling or floor n, to which the radiatoris secured, so that the room above that in which the radiator is locatedmay be heated.

In order that the air may have free access to the heating-tubes,supports or legs P are provided. These supports or legs are of anyapproved construction and are secured to the radiator and to the flooror ceiling of the l room, according to the position in which theradiator is placed.

What we claim isl. In a radiator, the combination, with a chamberprovided with a top plate and a bottom plate, of a partition slidablebetween the said top and bottom plates and having the extent of itsmotion limited by them, guides for the said partition, means for slidingthe partition, and inlet and outlet pipes connected to the said chamberon opposite sides of the said partition, substantially as set forth.

2. In a radiator, the combination, with a chamber provided with an inletand an outlet, and guide-rods secured in the said chamber; of adamper-plate arranged between the said inlet and outlet and' providedwith iianges which slide on the said guide-rods; and means for slidingthe said damper-plate, substantially as set forth.

3. In a radiator, the combination, with a chamber provided with a topplate and a bottom plate each of the said plates having two openings forue-pipes5 of a partition slide able between the said plates and havingthe extent of its motion limited by them, guides for the said partition,means for sliding thc said partition, an inlet and an outlet iiuepipeconnected to two of the said openings on 'opposite sides of the saidpartition, and cover-plates closing the remaining two openings,substantially as set forth.

In testimony whereof We affix our signatures in presence of twoWitnesses.
